Weathered meteorite.

On freshly fallen meteorites fusion crusts are usually smooth and glassy, although they might be rougher if the meteorite broke apart during atmospheric entry. On ordinary chondrites (87% of stony meteorites), they are usually usually black, although they might be reddish on weathered meteorites. 3. Fresh meteorites will have a dark gray or black surface. Weathered meteorites will appear brown or rusty. 4. The surface of most meteorites -- particularly if they have fallen recently -- will exhibit a "fusion crust," caused by burning in the upper atmosphere.

Meteorites are divided into three basic groups: irons, stones, and stony-irons. Practically all meteorites contain a significant amount of extraterrestrial iron and nickel, so the first step in identifying a possible meteorite is the magnet test. Iron and stony-iron meteorites are rich in iron, and will ...

It is like the glaze on ceramic ware. Usually, fusion crust is black because of iron in the meteorite. But sometimes it is brown or greenish or even clear. It will usually have small cracks and a texture like leather. Iron meteorites and stone meteorites can have fustion crust, but a few--very few--freshly fallen meteorites have none at all.

Weathered ordinary chondrite. A weathered ordinary chondrite is a stony meteorite that has been exposed to the elements on Earth's surface for an extended period of time.

Some iron meteorites contain oxygen-bearing phases: chromite, phosphates, and silicates, which can be isotopically analyzed to search for genetic associations with stony meteorite groups. There is a clear isotopic and chemical connection between the group IAB irons and winonaites (one class of primitive achondrite, discussed below).

Iron-nickel metal. More than 95% of all meteorites contain iron-nickel (FeNi) metal. As a consequence, meteorites have concentrations of nickel that are much greater than that of nearly any terrestrial rock. “Iron-nickel” means that the metal is mostly iron but it also contains 5-30% nickel.Weathered meteorites. ~95% of meteorites contain between ~10 and ~20% metallic iron when they fall. This iron begins to rust after landing on Earth: a freshly fallen meteorite won’t be rusty, but ~95% of meteorites will begin to show at least minor oxidation within weeks to months. After a few decades, they’ll be ~thoroughly rusty. Predicting the weather has long been one of life’s great mysteries — at least for regular folks. Over the years, you’ve probably encountered a few older adults — maybe even your own grandparents — who made some weather predictions based on ...Iron was available to some of the world’s oldest civilizations as early as 1500 B.C., although some accounts place its discovery as far back as 2500 B.C.
